The problem I'm having is that I import products with Magmi (magento product import open source solution), but I don't see the product image on the front end. I need to know which table in magento database contains image names so that I could maybe feed it somehow directly...
catalog_product_entity_varchar
The table above stores the values that will link your images, but you need check first with the eav_attribute table to find the correct attribute_id key that will reference the image. While this answers your question, I want to remind you that making database changes directly is strongly discouraged. Hope this makes sense.
